THOMAS c. MoDANIEL AND RICHARD M. FRAWLEY, or Roorrnsrnn, NEW OR WINDOW-SCREEN.

Application filed. April 26, 1916. Serial N 0. 93,786.

To all whom z'tmay concern:

Be it known that we, THOMAS G. M0- DANIEL and RICHARD FRAWLEY, citizensof the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification. This invention relates to improvements in spring-controlled window screens. It has for its object a construction in which the screen is prevented from escaping from its vertical guideways, while being'raised or lowered, and which at the same time permits the screen to be removed after having been rolled up without disturbing the vertical guideways.

In the drawings Figure 1 is a front view of a screen and its housing;

Fig. 2 is a vertical section on the line a.a

of Fig 1;

Fig. 3 is a partial sectional view, enlarged, taken on the line b6 of Fig. 2; and

Fig. 4 is an enlarged vertical section, on the line cc of Fig. 3. I

The spring-actuated roller 1 of usual construction is supported on its shaft 2 by the end plates 3 of the housing 4. The screen 5 has at its lower edge the reinforcing strip 6, which movesin vertical guideways 7 7 on the casing. The upper ends of the guideways 7, 7 terminate some distance below the roller, so that by permitting the screen to roll up fully on the roller the ends of the reinforcing strip 6 are withdrawn from the guideways 7, 7, and the rolled up screen may be removed from the window. I

But unless the housing 4 is removed for the purpose of removing the screen, the housing bears yieldingly at its loweredge against the screen, on both sides 'of the frame, above the points where the guideways terminate, thus holding the reinforcing strip 6 in against the frame, so that it enters the guideways when drawn down from the upper-most position which it takes when the screen is wound up as far as'it will go.

In order to keep the reinforcing strip 6 in its guideways 7 7 while the screen is being raised and lowered, a cross-bar 8 is employed on the lower end of the screen, back of the reinforcing strip, that is slightly narrower than the distance between the sides of the casing, so that as the screen is raised and lowered this cross-bar 8 is in close proximity- Specification of Letters Patent.

to the sides of the window frame and prevents one end of the reinforcing strip 6 from moving upwardly in advance of the,

other, as frequently occurs in manipulating screens and curtains. arranged. in this manner. i A bolt 9 for locking the scree'n'in extended position is shown Thisisadapted to f "the casing near the's'ill. l I

The cross-bar 8 serves another function.

It underlies a top rail 10 of the window' frame so that when the-screenis rolled up beneath the housing 4-, thiscross-bar8 will come in contact with the casing and prevent the screen from being wound up on the roller so as to carry it out of reach. As it is, the crossbar 8 is accessible and affords an adequategrip when the screen is to be drawn down. a The screen may be reinforced at intervals by spring strips 11 which are secured transversely of the screen. These strips prevent the sagging of the screen and at the same time have their ends working in the guides. What we claim as our invention and desire to secure by Letters Patent is: I

1. In combination with a window frame, a roller mounted at the top of the frame, a closure adapted to be wound on the roller and overlapping the side members of the frame, guides on the front faces of said side members for the side edges of the closure,

saidguides being spaced at their upper ends from the roller and the upper rail of the frame, a housing for the roller and the 010- sure projecting :below the upper rail of the frame, said housing being open at the rear and having a lower yieldingly mounted free edge arranged to permit the free edge of theclosure to pass the same in either di-, rection and lying in close proximity to the guide rails so that itacts as a guide to diroot the free edge of the closure to the guides when the free edge is withdrawn from the closure.

2. In combination with a window frame, a roller mounted at the top of the frame, a closure adapted to "be wound on the roller and overlapping the front faces of the uprights of the frame at its side edges, guides for the side edges of the closure securedto the front faces of the uprights, said guides being spaced "at their upper ends from the top rail of the window frame, a housing for the roller and the closure, the housing being open at the rear below said top rail and having its free lower edge lying in close proximity to the guide rails so that it acts as a guide to direct the free edge of the closure to the guide, and a cross bar secured to the free edge of the closure and lying between the uprights with its ends arranged to cooperate with the uprights to guide the closure to the guides and its upper part arranged to cooperate with the under side of the top rail of the window frame to maintain the free edge of the closure in a position where it may be reached from the open rear side of the housing.

3. In combination with a window frame, a roller mounted at the top of the frame Gopies of this patent may be obtained for five cents each, by addressing above the lower surface of the top rail of the latter, a closure wound on the roller said closure overlapplng the side members of the frame and having means near its free edge &

for cooperating with the under face of the top rail to limit the upwardmovement of the free edge of the closure, and a housing covering said roller, open at its rear below the top rail of the frame, and having a yieldingly mounted free edge below said top rail,v overlapning the side members of the window frame to bear upon the closure as the latter is drawn downwardly.
